2. 23 pairs of autosomal chromosomes and 2 Y chromosomes
3. 22 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome
4. 23 pairs of autosomal chromosomes, 1 X chromosome, and 1 Y chromosome

Best ResponseYou've already chosen the best response.2for the first one you need to remember the diploid number is 46. Out of them two are determining the sex either XX for woman or XY for men; For the second capital stands for a dominant allele.

Best ResponseYou've already chosen the best response.2so you have 44 autosomal chromosomes. that makes 22 pairs then a male is XY. For the second you need to find pairs for which the capital letter make a similar combinaison. the first one for example the left proposition will express IA when the right will express IAB. clearer like that?

Best ResponseYou've already chosen the best response.0Yeah it is thank you! Can you help me with this last one? For the pedigree in Figure 14–6, shaded symbols represent afflicted people. Males are squares; women are circles. If the trait is a sexlinked trait carried on the X chromosome, what is true about the mother represented by circle 1? She has two alleles for the disorder. She has one allele for the disorder. She has no alleles for the disorder. She has the genotype XXY.

Best ResponseYou've already chosen the best response.2. The mother in circle 1 (also true for 6) caries the allele for the disease but does not have the disease. As the disease is not seen at all generations it indicates a recessive allele is leading to the disease. So she must have another nonmutated allele.
